3 Qiaims. ((11. ML-18) This application is a division of my application Serial No. 141,884, filed September 29, 1961, and relates'particularly to improvements in package holders forconical yarn packages in winding machines. The invention provides an acceleration of the taper of the conical winding package, a retraction of the package axially of the drive roll, minimizes the extent to which any skewed relation may exist between the package and drive roll, renders the relation of the package to the drive roll certain by positive mechanical connections at all stages of movement of the package holder, and accomplishes these objects by Simple sturdy structure.

In the accompanying drawings:

FIG. 1 is an elevation showing a winding unit including the package holder of this invention;

FIG. 2 is a plan view showing the Winding package holder; and 7 FIG Sis a plan View on a larger scale and partly in section of the cone holder of FIG. 2.

Although the winding head 69 may be provided with a grooved package-driving roll that also traverses the winding yarn to distribute it on the winding package, the preferred head shown has a roll 85 which is suitably driven, for frictionally rotating the yarn package, and a separate yarn-traversing thread guide 72 which is reciprocated by a helically grooved cam at a variable speed which is, in known mannenfaster when near the tip end'of the package and slower when near the base end of the package.

The winding package is received-between the two arms of a generally U-shapecl yoke 90. The left of these arms carries a rotatable socket 91 for the conical tip of a paper cone C, FIG. 3, the socket turning in a ball bearing 91a. Slidablymounted in a boss d2 at the end of the other arm of the yoke a shaft 93 carries a disc 94 turning on a ball bearing 94a. Disc 94 carries a rubber ring 93 is yieldingl-y urged to the left by a lever 95 which is pivoted at 97 and biased by a spring 98. The disc 94 95 engageable with the interior surface of the cone. vShaft v shift along said package and drive roll. vThe yoke iii isclamped by extensions 9? to a'rod 109 whichis supported bybearings 101a and 101!) in which the rod 1M) can both rotate and move lengthwise. These-bearings define an axis for red- 1% which is inclined to. the axis of thepackage drive f roll, therod axis where it' approaches 101a being more remote from the package-drive roll axis than'where the 3 around said axis. r

3,139,239 Patented June 30., 1964 "ice rod axis approaches 10%. The amount of this inclination can readily, as in the machine illustrated, be made such that the cone axis continually increases its inclination to the drive roll axis as the package grows. The drive roll axis is indicated at x in FIG. 1.

Reference has been made to the rod 105 being capable of sliding in the bearings ifiia and 1011). This is for the purpose of retracting the winding cone in the direction of its larger end as the winding progresses. A bracket the movable with the yoke carries the inner element of a spherical bearing lilS. A stud 106 fast on the frame of the winder head carries the inner element of another spherical bearing 1%. The two other elements of the two spherical bearings are coupled by a tie-rod 109. Thus bearing m5 is constrained to move in an are around bearing 1% as the winding package grows. As the yoke 90 rises it and its red 1% must shift to the right in FIG/2 and when a new empty cone is applied, and the yoke is lowered to place the cone on its drive roll the yoke is restored to the left.

I claim:

1. A Winding machine for conical yarn packages including a package-driving roll, a yoke including means for rotatably holding the two ends of a yarn-receiving cone, means mounting the yoke for pivotal movement around an axis whichis inclined both vertically and horizontally to the line of nip between package and roll so as to estab-.

, lish a positive relation between the rates of movementof the two ends of the cone away from the roll, and a link pivoted to the yoke and to a point fixed relative to the location of the drive roll for constraining the yoke to a longitudinal shift along said inclined axis as the yoke turns around said axis.

2. A winding machine for conical yarn packages including a package-driving roll, a yoke including means for rotatably holding the two ends of a yarn-receiving cone, means mounting the yoke for pivotal movement around an axis which is inclined bothvertically and horizontally to the line of nip between package and roll so as to establish a positive relation between the rates of movement of the two ends. of the cone away from the roll, said mounting means including bearings spaced along said inclined axis and portions movable with said yoke and slidable and rotatable in said bearings, and a link pivoted Y to the yoke and to a point fixed relative to the location of the drive roll for constraining'the yoke to a longitudinal inclined axis as the yoke turns around said axis.
